Propagation and Seedling technique of lobular Privet

Lobular Ligustrum lucidum belongs to Oleaceae, Ligustrum lucidum, evergreen or semi-evergreen shrubs. Also known as small leaf holly, small ash tree. It is a hedge material in the garden, and can be used as the rootstock of sweet-scented osmanthus, cloves and other trees. Strong sex, cold tolerance; strong root tillering; resistance to pruning. It can be propagated by sowing, cutting and ramet, but mainly by sowing.

1. Sowing seedlings from October to November, when the drupe is purple-black, it can be harvested and sowed immediately after harvest, or it can be dried and stored until March of the following year. Soak the seeds in warm water for 2 days before sowing, and sow the seeds after soaking. Using strip cutting, strip spacing 30CM, sowing width 5-10CM, deep 2CM, covering fine soil after sowing, and then covered with straw. Pay attention to watering and keep the soil moist. After the seedlings are unearthed, the straw is removed step by step, and thin fertilizer can be applied when the branches and leaves are slightly developed. When the seedling height is 3-5CM, it can be interseedling, and the plant distance is 10CM. Seedlings generally grow slowly and can be used as hedges at the age of 2 years.

2. The cutting time of cuttage is 3murm-April or August-September. At the beginning of winter, the branches of the same year were cut into 15-20CM, and then stored in sand. After 4 months of sand storage, the healing tissue could be formed. When the cuttings were cut in spring in the following year, it would be easier to survive, and the survival rate would be doubled after soaking the branches with naphthylacetic acid. The row spacing of cuttings is 20 × 30CM, and the depth is 2 × 3 of cuttings. Water frequently after insertion to maintain proper humidity. Cuttings stored in sand can take root after being planted in spring for a month. Autumn cutters can not take root in that year, but only form healing tissue in winter and can not take root until the following spring. It will be managed for one year after survival, transplanted before germination in the spring of the following year, and can be used as rootstocks in the third year. If you want to obtain the grafting rootstock one year earlier, you can select the sturdy annual branches in autumn, cut the cuttings with about 25CM, and cut them according to the row spacing of 30 × 30CM in the following spring after sand storage, which can take root and survive in the same year, and can be used as the grafting rootstock in the second year.

3. After the tillers with roots were cut in spring, the seedlings were planted in the seedling field and watered when planting. 4. It is suitable for tending and management transplantation from February to March in spring and also in autumn. Need to bring earth balls, planting should not be too deep. For example, when planting, fertilize at the bottom of the hole to promote growth. If it is used as a hedge, it can be pruned properly and pay attention to pruning withered and diseased branches. The main pests are green insects, blow cotton shell insects, etc., and attention should be paid to prevention and control.

Ligustrum lucidum is a plant of the genus Ligustrum lucidum of Oleaceae, which is resistant to many kinds of poisonous gases and is an excellent anti-pollution tree species. Resistant to pruning and strong germination. The following conditions should be paid attention to when breeding.

To sow and reproduce:

The florescence of lobular privet is from July to August and the fruit ripening stage is from October to November. The drupe is purple-black when it is ripe and can be harvested. The harvested fruit is ripe, washed and dried after stacking. Then it will be sown in autumn. It can also be dried and hidden in the shade. It will be sown in spring the following year.

Before sowing, the seeds of dry storage seedlings were soaked in warm water for 1-2 days. Seedling seeds can be sown after absorbing enough water to expand. Broadcast on the Internet. The line spacing is 30 cm. The sowing area is 5 cm 10 cm and the depth is 2 cm 3 cm. After sowing, the soil is covered with fine soil, covered with grass, watered and kept moist. After the seedlings were unearthed. Remove the cover gradually. When the branches and leaves spread slightly, apply thin fertilizer. The height of the seedling is 3cm to 5cm. The seedlings were fixed according to the plant spacing of 10 cm. The growth of seedlings is slow and the management is extensive.

Cutting propagation:

Hardwood cuttings were carried out from February to March. The branches of the same year were collected in autumn, cut into 15cm and 20cm long for cuttings and stored in sand. After 3-4 months, the healing tissue was formed. It is easy to survive if you insert it in the next spring. Cutting according to the row spacing of 20 cm to 30 cm, and the cutting depth is 2 cm 3 of the length of cuttings. Pour water thoroughly after insertion, often keep the soil moist and avoid stagnant water. It took root 1 month after insertion. Autumn cuttings can not take root in that year, but can only form healing tissue in winter and can only take root in the next spring.

Softwood cuttings can be carried out from June to July, and semi-lignified branches can be used for cutting.

Ramet propagation:

Ligustrum lucidum has strong sprouting ability. Many sprouting seedlings will be produced around the rhizosphere of the mother plant. Before sprouting in spring, the sprouting seedlings around the rhizosphere of the mother plant were dug out and planted separately with roots. Or dig up the whole mother plant and divide it into several clumps with a sharp blade, each with 2-3 branches and roots, and planted in clusters. In order to improve the survival rate, the branches and leaves of the aboveground parts can be trimmed to reduce water evaporation. Plant according to the row spacing of (30-40) cm / (50-60) cm, and then water thoroughly. Transplantation is suitable for both spring and autumn, and the survival rate is high. It is not necessary to bring a complete earth ball for transplantation.

Cultivation of large seedlings:

The large seedlings of lobular privet are generally cultivated into thickets, spheres, and natural shapes used as hedges. As a hedge, it can promote more branches to sprout at the base and form plump shrubs through heavy cutting. As a sphere, it can be pruned repeatedly according to the spherical hemp in a year to form a plump ball. It is worth noting that the lobular privet is decorated into a ball, appears to be more relaxed, evacuated, not as tight as the small wax ball. Compact. As a natural shape, there is no need for more pruning, only withered branches, overlapping branches and interference branches can be trimmed.
